A recent horse event in Ogden, UT may have exposed horses to EHV-1.
What is Equine Herpesvirus-1
Equine herpesvirus 1 (EHV-1) is one of a large group of DNA viruses causing potentially serious disease in horses and other species. EHV-1 has two forms – one that causes abortion in mares and one that causes respiratory infection and neurological symptoms. The most recent outbreaks of concern have involved the EHV-1 respiratory/neurological form of the virus.
EHV-1 is contagious and is spread by direct horse-to-horse contact, by contaminated hands, equipment and tack, and, for a short time, through aerosolization of the virus within the environment of the stall and stable.
The virus is not a threat to human health. There is currently no vaccine labeled to protect against the neurological strain of this virus. There is a vaccine that may protect against the abortive and respiratory forms. If you feel your horse may have been exposed at a recent event, please contact your veterinarian and follow appropriate biosecurity and appropriate quarantine practices to prevent further spread of the disease.
